Patent number: 10247105Abstract: An air turbine starter includes a transfer tube having a lubrication inlet and a lubrication outlet configured to allow fluid to flow therethrough. A valve is positioned within the transfer tube including a spring. The spring is configured to selectively allow fluid flow within the transfer tube based on fluid pressure differential across the valve. The spring can have three positions: a first position configured to prevent flow within the transfer tube, an intermediate position configured to allow free flow of fluid within the transfer tube, and a compressed positioned to prevent flow to the lubrication outlet.Type: GrantFiled: January 8, 2016Date of Patent: April 2, 2019Assignee: Hamilton Sundstand CorporationInventors: Matthew A. Slayter, Jeff A. Brown, Benjamin T. Harder

Patent number: 8613142Abstract: A method of manufacturing a gear cluster from a first gear body and a second gear body comprises producing a first set of gear teeth on the first gear body such that each tooth on the first set of gear teeth has a first pitch point. The second gear body is axially aligned with the first gear body. A timing position for a second set of gear teeth on the second gear body is determined by dimensioning from the first set of gear teeth. A second set of gear teeth on the second gear body is produced based on the timing position and each tooth on the second set of gear teeth has a second pitch point. The gear cluster is inspected for timing position by measuring a reference dimension between the first pitch point and the second pitch point.Type: GrantFiled: July 30, 2010Date of Patent: December 24, 2013Assignee: Hamilton Sundstrand CorporationInventors: Matthew Slayter, Charles E.
